This is a Phaser port of the popular card game Set. Each card has a number of properties:
Shape - either circle, square, or cross Number - one, two, or three shapes Color - red, green, or blue Filling - either solid, clear, or grey
A group is a set of three cards, where each property is either identical, or different amongst all three cards. Two cards with an identical property, and one different card, does not a group make.
Feel free to fork and modify at your whim.
